(B) Given: Emf of the battery, $E = 12 \, V$ Internal resistance, $r = 2 \times 10^{-2} \, \Omega = 0.02 \, \Omega$ Current drawn by the starter motor, $I = 80 \, A$ When the starter is $ON$, the battery supplies current to the motor. The terminal voltage $V$ is given by the formula: $V = E - Ir$ Substituting the given values: $V = 12 - (80 \times 0.02)$ $V = 12 - 1.6$ $V = 10.4 \, V$ Therefore, the terminal voltage when the starter is $ON$ is $10.4 \, V$.
